The startup Plenty has raised $260 million from investors, including Jeff Bezos and SoftBank, to transform agriculture with a type of indoor tech known as vertical farming. Seven former employees told Business Insider that Plenty's leadership repeatedly touted expectations for the company that did not materialize during their time at Plenty. Four of the people said they felt unsafe at work on more than one occasion. Some of the insiders' concerns were with Plenty's technology during their time there; others centered on public statements they feel were, at best, overly ambitious and, at worst, misleading.
